    Abstract: 在許多企業的營運資金裡,存貨成本通常佔有相當大的比重,因此若能做好存貨管理,除了可以減輕企業資金的壓力,還能間接增加公司獲利能力。如何在低庫存管理成本、高服務品質與生產績效間尋求平衡點,一直是目前企業界所努力追求的目標。1915年Harris率先提出「經濟訂購量」(EOQ)公式,但其模型假設條件太多,導致實際運用時,受到很大的限制,因此陸續有許多學者針對不同的條件提出各種存貨模型。
    The inventory always have a higher proportion of the cost in a company, therefore having a good management of inventory control could make a higher profit. The goal of the company is to balance the low-inventory control cost, high quality service and production performance. In 1915, Harris developed an EOQ model with many assumptions, therefore it was difficult to be applied in the real world. However, many scholars modified its assumption according to different conditions.
    Traditional EOQ model assumes retailers own a warehouse without capacity limitation. However, in the real world company has fixed capacity warehouse. Thus while the company has a large stock because of the large order, they need to rent another warehouse to hold excess stocks. Moreover, traditional EOQ model does not consider defective items, even poor-quality items do exist during production procedure. In addition, the demand rate does not always stay constantly, it would change with different price. Thus, considering price-dependent demand will make model more reasonable.
    In this thesis two inventory models are formulated. In Chapter 2 we assume that supplier provide quantity discount for retailers, In Chapter 3 we extend the model in chapter 2 with supplier allows a specified credit period to the retailer for payment without penalty. The goal of two inventory models is to determine maximize the profit per unit time. For each inventory model, we establish algorithm to determine the optimal strategy and numerical examples are given to illustrate the solution procedure. Also, sensitivity analysis is conducted for the parameters of the models. Finally, Chapter 4 provides the conclusions of this thesis and some suggestion future research.
